Lizards

I don't believe this is of major concern even though I have a couple of hives where the lizards like to hang out. This lizard was working a bait hive and picked off a few scouts however the swarm still moved in and chased the lizard off.

Spiders

This is a rather rare sight to see, a spider on golden rod. Many of my hives have spiders living between the inner and outer covers or underneath the hive, however I see more of other insects in their webs than bees.  I have only once found a spider inside of the hive once, during an inspection in February 2019 one took up residence on the comb near the entrance of a weak and struggling colony.

Small Hive Beetles

The adult beetles can be found in nearly every hive. So long as the is strong and healthy they rarely present a problem. I usually only see increased numbers and problems during a dearth when too many empty supers are on the hive. I find that compressing the hive does wonders to chase these pest away.

Wax Moth

It is very rare indeed to see an adult moth in the colony. While the larva appear to look very similar to that of the beetle it can usually be distinguished by the presence of web look tunnels though the comb.

There are two types of moths the Greater and Lesser which one is this larva from I have no idea. My guess is that it is from the Lesser as I have found them on some comb left out after a  removal from a home.

Varro Mites

Mites on drone larva.

The mites themselves are not very nice, but the viruses they carry are much worse and can collapse  even the strongest of colonies in a very short period. It is a good practice to monitor their progress by doing mite counts several times a year and treating when the numbers become elevated.  I personally tried using a chemical treatments several times, however the side effects on the bees were not to my liking. I am choosing the way of brood breaks now and terminating and destroying all contents of the hive before the colony collapses. If the hive is allowed to collapse then the other colonies will come to rob them and spread the problems. Thankfully I have only had to do this once.

Tracheal Mite

Have only had one confirmed encounter with this one in the spring of 2017. It is extremely  hard to detect in a hive as it's symptoms are not very distinguishable from that of viruses or nosema. The only sure way to determine its presence is through microscopy. The use of a dissecting  microscope is much easier than trying to use a compound although it can be done.

Nosema

Unfortunately this is most likely the second most damaging  problem found in the hive  behind Varro. The original strain that affected bees was accompanied by dysentery, however it is rapidly being displaced with a strain that has little to no symptoms. The only way to confirm its presence and level of infection is with a compound microscope using at least 400x magnification. On the brighter side the bees can overcome this one if the levels are not too high and the quality of forage is good.
